How to get rid of automatic Google translation?

I am using Slimbrowser, and I am constantly getting a message window at
top that says: "This page has been automatically translated", along
with a Google icon. This happens when I am accessing all kinds of Web
pages which (a) having nothing to do with Google, and (b) are in
English to begin with, and have no need of translation. Can anyone tell
me how to get rid of this annoying translation feature?
